Fire, explosion, electrical shock or pressure release could occur and cause death or serious injury if these safe service procedures are not followed. Preliminary Precautions You are working in a potentially dangerous environment of flammable fuels, vapors, and high voltage or pressures. Only trained or authorized individuals knowledgeable in the related procedures should install, inspect, maintain or service this equipment. Emergency Total Electrical Shut-Off The first and most important information you must know is how to stop all fuel flow to the pump and island. Locate the switch or circuit breakers that shut-off all power to all fueling equipment, dispensing devices, and submerged turbine pumps (STPs). WARNING The EMERGENCY STOP, ALL STOP, and PUMP STOP buttons at the cashier s station WILL NOT shut off electrical power to the pump/dispenser. This means that even if you activate these stops, fuel may continue to flow uncontrolled. You must use the TOTAL ELECTRICAL SHUT- OFF in the case of an emergency and not only these cashier station stops. Total Electrical Shut-Off Before Access Any procedure requiring access to electrical components or the electronics of the dispenser requires total electrical shutoff of that unit. Know the function and location of this switch or circuit breaker before inspecting, installing, maintaining, or servicing Gasboy equipment. Evacuation, Barricading and Shut-Off Any procedures requiring accessing the pump/dispenser or STPs requires the following three actions: - An evacuation of all unauthorized persons and vehicles using safety tape, cones or barricades to the effected units - A total electrical shut-off of that unit Read the Manual Read, understand and follow this manual and any other labels or related materials supplied with this equipment. If you do not understand a procedure, call a Gasboy Authorized Service Contractor or call the Gasboy Service Center at 1-800-444-5529. It is imperative to your safety and the safety of others to understand the procedures before beginning work. Follow the Regulations There is applicable information in NFPA 30A; Automotive and Marine Service Code, NFPA 70; National Electrical Code (NEC), OSHA regulations and federal, state, and local codes which must be followed. Failure to install, inspect, maintain or service this equipment in accordance with these codes, regulations and standards may lead to legal citations with penalties or affect the safe use and operation of the equipment.
